Thanks Guys! This combo is making 29 psi at 5300 rpm , at least on the dyno it is.
I think the reason the power feel off up top is that I actually hit my Knock correction, which is very low. I think with the more power it made just enough noise to add .1-.2 volts which touch the knock sensor setting. Only Time will tell how this combo holds up to more boost.. So far it is a perfect combo for what I have. I was getting just over 30 mpg on the highway. Showing the twin scroll was more efficient down low/ crusing.
Also I am using the Garret 1.00 housing, cause I feel garret makes a best housing. The 1.06 fits the garret, but not sure who makes it. I feel the 1.00 flows better then the 1.06, NO DATA to prove that, just from past experience.
So Far I give the TwinScroll the big thumbs up..that might change at 40 psi... LOL. But for basically 600 whp street car It seems like a great combo. Not sure how many people are going to go to 40 psi plus.

Im very impressed with the twin scroll improvements Freddy, especially when we compared it to my setup. You spool faster and make more power even with the 1.00 backside. Good test

T4...very nice results again freddy and nice job at the track last night. Im so glad i got my car back. Jimmy, the guys at The Shop and Juniors tuning did an awesome job once again.
I will post up my results in a thread after i go back on Wednesday and we turn up the boost on pump gas. Cant wait, this wastegate boost im running around on is a tease
